EQ Office is planning a golden anniversary celebration for Willis Tower, which topped out construction on May 3, 1973

Willis Tower Reaches 50th Anniversary After $500M Redevelopment

EQ Office, Blackstone’s U.S. office portfolio company, announced plans to celebrate Willis Tower’s golden anniversary and iconic status in Chicago’s skyline. Wednesday marked 50 years since the landmark’s original topping-out ceremony, where it stood as the world’s tallest building for 23 years. 

The tower was brought to life in 1973 by architecture firm Skidmore, Owings and Merrill when Sears needed a central office space for its employees. With a $500-million redevelopment project completed last year, EQ transformed the 110-story building. 

“As we experience this new era for Willis Tower, this is a moment to recognize our historic past while celebrating the future,” said Kirsten Ekdahl Hull, SVP, portfolio management, EQ Office. “Between our state-of-the-art office spaces, new restaurant options, sustainability enhancements and re-imagined Skydeck experience, we have approached this building as stewards of our community to ensure the Tower remains a fixture in Chicago for decades to come.”
